Jeffamine D-2000 Polyoxypropylenediamine 9046-10-0 Huntsman Crosslinking / Coupling / Curing Agents >> Amine Epoxy Resins Coatings >> Electrodeposition Metal >> Primer Slightly soluble in water Miscible in a wide variety of solvents JEFFAMINE D-2000 polyoxypropylenediamine is one member of a family of Huntsman Corporation’s polyamines having as their backbones repeated oxypropylene units. As shown by the above structure, D-2000 is a difunctional primary amine having an average molecular weight of approximately 2000. Its amine groups are located on secondary carbon atoms at the ends of an aliphatic polyether chain. D-2000 is fairly light in color and reasonably low in viscosity. Its vapor pressure is extremely low. D-2000 is completely miscible in a wide variety of solvents. It is, however, only slightly soluble in water. JEFFAMINE D-2000 polyoxypropylenediamine undergoes reactions typical of primary amines. Because of its unique structure, D-2000 has found wide use in epoxy systems. In such applications, it is rarely used alone, but rather in conjunction with other curing agents, particularly other JEFFAMINE products. The flexibility and toughness of epoxy systems can be enhanced very efficiently through the inclusion of D-2000. Again in conjunction with other JEFFAMINE polyamines, D-2000 is used in epoxy adhesives which are characterized by high peel strengths. An intriguing application for D-2000 is in epoxy systems for metal priming via cathodic electrodeposition (Eur. Pat. 70-550). Nonepoxy uses for D-2000 include oil recovery chemicals and polyamide fibers. D-2000 salts make good cutting fluids. Extremely low vapor pressure difunctional primary amine. Used n epoxy systems for metal priming via cathodic electrodeposition. Rarely used alone, but rather in conjunction with other curing agents. Enhances flexibility and toughness.
